[Superhart]

I sent my early wiper to John Holland. Very nice man, by the way. He called me very disappointed saying that the inside of my wiper housing had multiple blisters and the side walls were warped. In other words, the unit I paid $150 for was total junk and could not be resurrected. Fortunately, I had a later unit that does work perfectly and I installed that one without a hitch. I rigged up the vacuum lines to draw manifold vacuum when the wiper is not in use. That is necessary to maintain the blade in the PARK position. In order to avoid the wiper slow down when under acceleration I installed a small Hella vacuum pump on the firewall usually used for high performance power brake units. When the wiper is in use I flip the pump switch on and no slow down. A pair of vacuum check valves keep the pump from disturbing manifold vacuum. Manifold vacuum is around 18" mercury whereas the pump makes up to 28". It has worked well thus far.
